Invoice calculation formula with example
-
Use the formula:
Total Amount = (Subtotal + Taxes) – Discounts -
Where:
Subtotal = Sum of all product/service amounts (Quantity × Rate)
Taxes = GST or applicable tax percentage on subtotal
Discounts = Any promotional or client-specific reductions -
Example: A freelancer provides services worth ₹50,000 with 18% GST and a ₹2,000 discount.
Subtotal = ₹50,000 │ GST = 18% of ₹50,000 = ₹9,000 │ Discount = ₹2,000 -
Totals:
Total Amount = (₹50,000 + ₹9,000) – ₹2,000 = ₹57,000
Final Payable = ₹57,000

Are business loan EMI calculators accurate?
Yes, EMI calculators provide accurate estimates based on the input values. However, actual EMIs may vary slightly due to processing fees and other charges
What happens if I miss an EMI payment?
Missing EMIs can result in penalty charges, negative credit score impact, and potential legal action. Always communicate with your lender during financial difficulties.
Can I get tax benefits on business loan EMIs?
Yes, both principal and interest components of business loans may qualify for tax deductions under relevant sections of the Income Tax Act.
